To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.
15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been
The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20
So take the 21 from before, and if you add -1, you get 20!
So, x= ➖1⃣!!!!!!! (That's a -1)
The linear function with values of f(-1)=8 and f(5)=6 is f(x) =
.
What is linear function?
A straight line on the graph has the equation or formula y = f(x) = px + q is linear function .One independent and one dependent variables are present. X and Y are the independent and dependent variables, respectively. P is the y-intercept or constant term, and it also represents the value of the dependent variable. A straight line on the coordinate plane is represented by a linear function.
Here the given values are f(-1)=8 and f(5)=6.
We know that f(x)=y , Then the points are (-1,8) and (5,6).
Using slope formula ,
=> slope m= 
=> slope m = -2/6=-1/3
Now using slope formula,
=> 
=>y-8=-1/3(x+1)
=>3y-24=-x-1
=> 3y=-x+23
=> y = 
Hence the linear function is f(x) =
.

Answer:
3.6 miles
Step-by-step explanation:
do 4.5/1.25 because that is the unit rate. when you do that you get 3.6 miles in an hour
C. 71%
It is really .708 but just round it up to .71.
